ratemeqoetamaia Application filed February 26, 1912. Seri/a1 No. 680,128:

To all whom t may concern f Be it known that I, FRANK E. FRIsBEE, acitizen of the United States, residing at Des Moines, in the county of Polk and State of iowa, have inventeda certain new and useful improvement in Window-Frames, of which the following is a specification.

The object of m invention is to provide a window frame o simple, durable and inexpensive construction in which the parts that come in contact with the sliding sashes are made wholly of sheet metal in a strong and durable manner and also so that they may be readily and easily applied to a building.

My object is further to provide a window frame of this'class with adjustable stops so arranged that the operator may readily and easily cause the stops to withdraw into the interior of the frame to thereby leave the surface of the frame unobstructed, thus per-v mitting the window sashes to move freely inand out of the window frame so that they msg be easily and quickly cleaned.

further object is to provide means for adjusting the stops so that they may be made to bear upon the sashes with any def sired amount of pressure and so that the swelling or contracting of the wood in the sashes may be compensated for and the sashes may be made so that they will slide up or down with any desired amount friction or so forced.` firmly against the central stop and against each other to make tight joints.

A further object is to provide improved means for locking the stopsin any position of their adjustment so that the amount oi' pressure sashes will remain constant at the point at which the locking device is fixed.

My invention consists in certain details, in the construction, arrangement and combination of the various parts of the device, whereby the objects contemplated are att-ained, as hereinafter more fully set forth, pointed out in my claims and illustrated in the accompanying drawings, in which:

Figure 1 shows a vertical, transverse, Sectional view through a window frame and window sashes embodying m invention. Fig. 2 shows an enlarged, detail view illus- .trating a part of a window frame provided with my improvement showing the inside of the frame. Fig. 3 shows an enlarged detail, sectional view on the line 3-3 of of v that the sashes may be bothapplied by the stops to the window Fig. 2. Fig. d shows a sectional view through the top of the window frame. Fig. 5 shows a detail, sectional view through one of the movable stops to show the links by which the stops are moved in and out. Fig. 6 shows a detail view'illustrating the spring for holding the locking device in any position in which it may be adjusted, and Fig. 7 shows a detail view illustrating the locking plate.

Referring to the accompanying drawings,

-my improved frame is seen to be composed of a number of smooth Hat boards 10 which are first placed in position instead of the ordinary window frames which are usually provided with grooves and parting stops, said boards being extended over the sides and top of the frame.

@n the inner surface of the board 10 on the sides of the frame, l first place a dat sheet metal strip'll having its ends -bent at ri ht angles over the ends of the board ecured to this sheet metal strip 1l is anotherstrip of sheet metal comprising an outer end portion 12 secured to 'and overlapping the end of the metal strip 11 and a number of straight portions 13 spaced apart from the strip 11 and having between them the grooved portions 14, there being preferably three of said grooved portions. The inner parts of said grooved portions are connected to the part 11 by rivets 15, thus firmly and securely uniting the two metal strips and holding the parts 13 accurately spaced a art from the sheet metal strip 11.

In eac of the grooves 14 is a parting. stop; the central one is made of a single piece o sheet metal and comprises two parallel sides 16 and a straight central portion 17 at right angles to the sides. This pai-'ting stop is of such size and shape as to be capable of sliding into the groove 14 so that its outer portion 17 is tiush with -the straight portions 13 and it is also capable of being projected outwardly from the straight portions 13 to form parting stops for the window sashes 18. rIhe parting stop in the outer groove 14: has its inner side beveled at 19, as shown in Fig. 3, and the inner parting stop has its' outer side beveled at 20, as shown in Fig. 3. rlhese beveled portions are designed to engage the inner surface of the lower sash and the outer surface of the upper sash and when said parting stops are in their extended positions the beveled portions tend to hold the two sashes firmly toward each other and against the central parting stop, and when the so that they are only partially inserted in their respective grooves, thebeveled portions will permit the sashes to freely slide between the parting stops. vBy this means the parting stops may be made to engage the sashes in such a manner as to tightly 'hold them against the central parting stop and against each other so that they may be adjusted and the sashes slide freely and loosely between them. As shown in Fig. 5 the parting stops are shorter than the grooves in the frame inl order to permit the sliding movement of the stops.

' In order to provide for jointly moving the parting stops in and out, I have pivoted on the interior of each parting stop an arm 21 extended toward the metal strip 1l. The lower one is provided with a square opening 22 and the upper one is provided with a pivot pin 23 which connects it with the part of the sheet metal strip that forms the groove 14. For convenience in assembling these arms 21, I preferably provide an inwardly extending lug 24 on the material at the bottom of the groove 14 on which the arm 21 may rest when being assembled.

In order to connect all of the lower arms 21 together so that they may be jointly moved, I provide a square shaft 25 which is extended through the parts of the material that forms the groove 14 and also through the square openings 22 of the arms` 21. This shaft turns freely in the openings through the parts forming the grooves 14 and when turned it will jointly move all of the lower arms 21, the limit of movement being from the horizontal position shown in Fig. 5 to a substantially vertical position with the parting stops wholly received into the grooves.

Under certain conditions it is possible the when the parting stops are in position to firmly engage the window sashes vertical movement of the window sashes might tend to move the partingstops either up or down and thus cause them to tighten or loosen relative to the sashes. In order to prevent this and for the purpose of locking the parting stops in any position in which they are placed, I have provided on one end of the shaft 25 an extensible coil spring 26 designed lto move the shaft 25 longitudinally toward the outer side of the window frame. On the inner end of the shaft' 25, I have provided a locking plate 27 provided with a series of notches 28. This plate is designed to be secured to the inner surface of the window' frame as shown in Fig. 2. Mounted upon the shaft 25 is an arm 29 having a lug 30 thereon, which lug is designed to enter the notches 28 on the plate 27. A crank 31 is detachably connected to arting stopsy are all moved outwardly a s ortv distance the inner end of the shaft 25 so that the said shaft may be readily and easily turned, and obviously when turned to another position it will be yieldingly held'by the s ring 26 holding the lug 30 in one `o the notches 28.

The top portion of the window frame, as clearly shown in Fig. 4, comprises a sheet metal strip 32 fixed to the board 33 which forms the top of the window frame. This metal strip 32 is provided with a single parting stop 34 formed in the material.

In order that the upper Window sash may be firmly held against the parting stop 34, I have provided a metal strip 35 having a substantially U-shaped rib 36 formed at one edge, the free end of which is designed to rest against the upper sash so that it will yieldingly hold the sash against the strip 34. Thel material of which the U-shaped rib is formed is suiiiciently resilient to allow for the ordinary contraction and expansion of the wooden sash so that a tight joint will be made at the top of the window sash under all ordinary conditions, thus dispensing with the necessity of making adjustable stops for the top of the sash.

One of the advantages of my invention is that lthe sides of the frame are made up of two pieces of sheet metal which may be readily and easily pressed or rolled into the desired shape without hand work and at slight expense. The metal need not be heavy for the reason that the two pieces are united by rivets at several points, thus brac- -ing and supporting `each other. These metal ranged for movement within the groovesformed in the sheet metal frame members so that when the parting stops are moved they will slide readily and easily.

The construction by which the two beveled parting stops may be made to force. the sashes firmly against the central parting stop and against eachother is of considerable importance. Furthermore the construction by which the parting stops may be locked in any position of their adjustment is advantageous for the reason that the sashes may be made to slide freely and easily regardless of the construction or expansion of the wooden sashes and if under certain conditions the sashes do not slide freely the operator need only turn the shaft 25 a part of a revolution, whereupon thepressure on one side of each sash is removed, or if the-sashes do not fit tightly enough the shaft 25 may be turned in the opposlte direction and the sashes will be firmly held against the central parting stop.
